[A new method of lacrymal derivation in the canalicular obstruction (author's transl)].

The authors believe that in their experience the best method of lacrymal derivation in the canalicular obstruction is the Jone's technique. However, the post operatoire complications are numerous in this method and therefore they are looking for a new procedure of lacorhinostomy: - the type of tube is a silicone tube which has the great advantage of not irritating the tissues; - the silicone tube is introduced into the lacrymal duct. After having used this technique for four years the authors are convinced that this is the best method.
